Concept:This question tests your ability to rearrange jumbled parts (P, Q, R, S) into a grammatically correct and meaningful sentence. The correct sequence is found by identifying the subject, the verb phrase, and the clause that completes the idea.
Explanation:First, identify the part that introduces the subject and main action. Part S ("many people today are willing to") gives the subject and the beginning of the verb phrase.
Second, find the part that completes the verb phrase after "to". Part Q ("surrender to the idea that") directly follows the "to" from part S and introduces the object of their willingness.
Third, the word "that" in part Q signals a subordinate clause. This clause is introduced by part P ("there is in all instance a single,"). So, part P follows part Q.
Finally, part R ("authoritative truth to be discovered and defended") provides the object of the clause from part P and gives a conclusive ending to the sentence.
Thus, the correct order is S → Q → P → R, which matches option D: SQPR.
Answer:The correct sequence is SQPR, which corresponds to option (D).
